When working with multiple actions in a Hololink, you may be hiding or showing objects, playing videos and pausing animations at the same time, with the same tap of an object or button.
This could give you a list of items that looks like this, with 4 actions for hiding objects :

But if we tag all the objects we want to hide with the same tag, in this case "objects_to_hide", we can hide them all together.

First we tag them like this:

Then we set a single hide object action, that calls all objects tagged with our new tag:

A Hololink where you can see the tagging system in action, is the Baby Stroller Configuration example, that you can open and edit by clicking on it in the Examples section. In the example, different baby strollers are hidden or shown, depending on which button is clicked, which gives the audience a dynamic and interactive experience.

Now you can use tags to show and hide multiple objects, changing the audience's view at the tap of a button or object.
